| Docker Container |
If you are find this article and start reading that mean you already know little bit about Docker. Docker is a platform for developing, shipping, and running applications inside lightweight, portable containers. Containers are a form of virtualization that allows you to package an application and its dependencies tog. Anyway, here are the Dockerize code that you are looking for?
How To Docker Container WordPress Website?
To run WordPress in a Docker container, you need to create a Docker Compose file that defines the services for WordPress and its database. Below is an example Docker Compose docker-compose.yml file for running WordPress:
version: '3'
services:
wordpress:
image: wordpress:latest
ports:
- "8080:80"
environment:
WORDPRESS_DB_HOST: db
WORDPRESS_DB_USER: wordpress
WORDPRESS_DB_PASSWORD: password
volumes:
- ./wp-content:/var/www/html/wp-content
db:
image: mysql:latest
environment:
MYSQL_ROOT_PASSWORD: root_password
MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: password
volumes:
- db-data:/var/lib/mysql
volumes:
db-data:
save this file as a docker-compose.yml and open a terminal in the project directory and run the following command to start the services:
docker-compose up -d
Access WordPress in your web browser by navigating to http://localhost:8080 (or replace localhost with your server's IP if running remotely). You can now complete the WordPress installation.
Make sure you have Docker and Docker Compose installed on your system before using this setup. You can customize this setup further based on your requirements, such as using different ports, database configurations, or using a specific version of WordPress.

How To Docker Container Laravel Application?
To run a Laravel application in a Docker container, you'll need to create a Dockerfile for your Laravel app and a Docker Compose file to manage the services. Below, I'll provide a basic example setup for running a Laravel app using Docker and Docker Compose:
# Use an official PHP runtime as a parent image
FROM php:8.0-fpm
# Set the working directory in the container
WORKDIR /var/www/html
# Install system dependencies and PHP extensions
RUN apt-get update && apt-get install -y \
git \
zip \
unzip \
libpng-dev \
libjpeg-dev \
libfreetype6-dev \
libonig-dev \
libxml2-dev \
&& docker-php-ext-configure gd --with-freetype --with-jpeg \
&& docker-php-ext-install gd pdo pdo_mysql mbstring exif pcntl bcmath soap
# Install Composer globally
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
# Copy the Laravel application files to the container
COPY . .
# Install PHP dependencies
RUN composer install
# Expose port 9000 and start PHP-FPM
EXPOSE 9000
CMD ["php-fpm"]
Create a docker-compose.yml file in your project's root directory with the following content:
version: '3'
services:
app:
build:
context: .
dockerfile: Dockerfile
ports:
- "8080:9000" # Map host port 8080 to container port 9000
volumes:
- .:/var/www/html
networks:
- laravel-network
networks:
laravel-network:
Open a terminal in your project directory and run the following command to build and run the Laravel app container:
docker-compose up -d
This setup uses the official PHP image for PHP 8.0, installs necessary dependencies, sets up Composer, and copies your Laravel project files into the container. The app is exposed on port 8080 on your host.
Remember to customize the Dockerfile and Docker Compose file as needed for your Laravel project, especially if you have specific environment configurations or additional services (example a database) required for your application.

How To Docker Container Django Application?
To run a Django application in a Docker container, you'll need to create a Dockerfile for your Django project and a Docker Compose file to manage the services. Below is a basic example setup for running a Django app using Docker and Docker Compose:
In your Django project's root directory, create a Dockerfile with the following content:
# Use the official Python image as a parent image FROM python:3.9-slim # Set environment variables for Python ENV PYTHONDONTWRITEBYTECODE 1 ENV PYTHONUNBUFFERED 1 # Set the working directory in the container WORKDIR /app # Copy the requirements file into the container at /app/ COPY requirements.txt /app/ # Install any needed packages specified in requirements.txt RUN pip install -r requirements.txt # Copy the rest of the application code into the container at /app/ COPY . /app/ # Expose port 8000 EXPOSE 8000 # Start the Django application CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]
Create a docker-compose.yml file in your project's root directory with the following content:
version: '3'
services:
web:
build:
context: .
dockerfile: Dockerfile
ports:
- "8000:8000" # Map host port 8000 to container port 8000
volumes:
- .:/app
networks:
- django-network
networks:
django-network:
Open a terminal in your project directory and run the following command to build and run the Django app container:
docker-compose up -d
This setup uses the official Python 3.9 image, sets up the necessary environment variables, copies your Django project files into the container, and runs the Django development server on port 8000. You can customize the Dockerfile and Docker Compose file as needed for your Django project, especially if you have specific environment configurations or additional services (example a database) required for your application.

Why Use Docker?
If you want to know more details about docker container then here are some key points to understand about Docker.
1. Docker Containerization
Docker uses containerization technology to package applications and their dependencies into isolated units called containers. Containers are similar to virtual machines (VMs) but are more lightweight because they share the host operating system's kernel.
2. Docker Image
A Docker image is a lightweight, standalone, and executable package that includes everything needed to run an application, including the code, runtime, libraries, and environment variables. Images are the blueprint for creating containers.
3. Docker Container
A Docker container is an instance of a Docker image. Containers run in isolation from each other and from the host system. They have their own file system, processes, and network, but share the host OS kernel, which makes them more efficient than traditional VMs.
4. Docker Engine
Docker Engine is the core component of Docker. It's responsible for building, running, and managing containers. Docker Engine includes a server, a REST API, and a command-line interface (CLI) for interacting with containers and images.
5. Docker Dockerfile
A Dockerfile is a text file that defines the instructions for creating a Docker image. It specifies the base image, adds dependencies, copies files, sets environment variables, and defines how the container should behave.
6. Docker Registry
Docker images are typically stored and distributed via Docker registries. The Docker Hub is a popular public registry, but you can also set up private registries for your organization. Docker images can be pulled from and pushed to registries.
7. Docker Compose
Docker Compose is a tool for defining and running multi-container applications. It allows you to specify the configuration of multiple containers in a single YAML file and then start and manage them with a single command.
8. Docker Container Orchestration
Docker can be used in conjunction with container orchestration platforms like Kubernetes and Docker Swarm. These platforms help manage and scale containers across multiple hosts, providing features like load balancing, automatic scaling, and high availability.
9. Docker Isolation and Security
Containers provide a level of isolation between applications, making it easier to manage dependencies and reduce conflicts. However, it's essential to configure containers securely, limit their privileges, and follow best practices to maintain security.
10. Docker Portability
Docker containers are highly portable, allowing you to develop an application on your local machine and then run it consistently across different environments, such as development, testing, and production, without worrying about differences in dependencies or configurations.
11. Docker DevOps and CI/CD)
Docker is widely used in DevOps practices and CI/CD pipelines because it simplifies the process of building, testing, and deploying applications. Containers make it easier to achieve consistency between development and production environments.
12. Docker Community and Ecosystem
Docker has a large and active community, which has led to the creation of many third-party tools, extensions, and plugins that enhance its functionality. These include monitoring tools, networking solutions, and more.
